How To: EGR Removal and Cleaning for Rough Idle Fix

[jimmybrite]

oh, mine would go below the first tick, so I would really idle low, but I wasn't aware that the first tick was 500

 

[protegeric]

if u clean ur IAC and EGR, and the car still dies occasionally (like mine) raise the idle to 1000 (i think normal idle is 750 or somethin close). it`s the only thing that i personally know for certain that is an easy fix. i thot someone was saying that their car was still havin some problems after cleaning one or both. no one?

wtf

oh and it seems to be all fixed now, when I have free time i'll check the idle Solenoid.I would have done it at the same time as my egr, but I couldn't find the proper torx bit

 

[jimmybrite]

I did, butttt for the first 25 miles, but it was still def better, I finished working on my car @ 9 pm sunday and I just went to mickey d's that night.. the next day, my car's like new..

how do you get the two bolts out if the are facing the throttle body?

 

[amsgator]

mine is idling around 450 ever since i installed my header. i dont know why...i checked the intake to make sure its on fine and not lose and it is...so if i clean this and it still does it i give up

There not facing the throttle body, they bolt up towards the throttle body.

 

[amsgator]

so where are the heads?

 

[Kansei]

the heads are on the underside of the intake manifold, where the EGR valve itself sits.

 

[amsgator]

ok. and the first tick is 500 rpms you said? mine idles at about the 2nd tick... is that normal? and if so why is it so shaky? it makes my shifter shake pretty bad. wasnt doin it til i put the header on, idk if that would cause it or not

 

[Kansei]

that's low, and that is why it is so shaky.

my car idled at ~690rpms on the last ct emissions report I have for my car, so that's just above the second tick.

 

[amsgator]

how can i get a reading of what it idles at? do i need a code reader or what?

well it idles at about the 2nd tick sometimes btwn the 2nd and 3rd.

idk if thats low or not... i dont c why the header would cause the drop though unless somehow the egr valve finally gave in

 

[Kansei]

yeah to get the actual number you'd need somethin to plug into your OBDII port, that's why I only know from my emissions certification paperwork.

You seem to idle right where I do, and I know that my EGR really needs to be cleaned again.

Hmm it still sounds like you have a vacuum leak somewhere. As someone mentioned earlier, spray some starter fluid (I think that's what they said? don't know where the post is now) around and see if the idle raises to track down a pesky vacuum leak.

 

[amsgator]

where do u spray it? i've never had to do it before. i am supposed to be cleaning the egr valve today if it doesnt rain. so i'll c if that helps at all. i didnt see the post about the vacuum leak

 

[amsgator]

and will a simple code reader be able to tell me the rpms?

 

[amsgator]

is there a way to do nething to see where the leak is coming from if there is one?

how important is the oil? i took mine out cause i had a rough idle, but never dipped. when i changed my clutch yesterday i decided to clean it hoping to fix the rough idle. so i cleaned it with brake cleaner and put it back together without oil. now my car jumps in idle when im about to stop and push in the clutch. any thoughts?

 

[amsgator]

i am cleaning mine today :-\ what kind of oil? i'll oil mine and hope it fixes it.

That's what mine started doing last week or so but I didn't do anything with the EGR since december...

 

[amsgator]

well i found a leak on the 2nd o2 sensor, i seafoamed it again to check for leaks and found that one, fixed it...didn't do anything. i think i may have town mount(s).

i got some pix and videos of what it is doing, so here they are

engine shaking- hard to tell but if you watch the wires and coil packs you can see, its easier to see in person

i dont think the muffler is supposed to shake like this?

and attached pic of passenger side mount and front mount. would the mounts be causing all this hell?? i dont see why the mounts would cause the engine to idle at the 2nd tach and make the shifter and cabin vibrate like hell and also the muffler....?

EDIT: added pictures

Marshmallow Motor mounts will do that for you.
